OIL-LAMP.

Specification of Letters Patent.

Patented Aug. a; rare.

Application filed April 14, 1914. Serial N 0. 831,799.

To all whom it may concern:

Be it known that I, SYDNEY HARRY SHER- wool), subject of the King ofGreat Britain, residing at :H to 50 Granville street, in the cityofBirmingham, England, have invented certain new and useful Improvementsin Oil-Lamps, of which the following is a specification.

The invention relates to an oil lamp internally fed by ascending gentleair currents induced by a small fan applied internally to the base ofthe lamp, and driven by a wound-up spring. In such a lamp the Ollcontainer is surrounded by an outer shell between which and saidcontainer a free annular space is left for the flow of air from theinclosed base of the shell to within the burner cone. The burner of sucha lamp is built up of three principle parts, burner body, burner cone,and globe or shade holder.

To this kind of oil lamp the invention solely relates, and provides thehereinafter built up of three principal parts, burner parts formed, andfitting each other, and the oil container, and inclosing shell, in aspecial manner, with the primary object of efliciently supporting theglobe or shade holder, and at the same time enabling the trimming of thewick to be easily performed.

The invention comprising said combination of parts is represented by theaccompanying drawings.

Figure l is a vertical section of the complete lamp. Fig. 2 is ahorizontal section of Fig. 1 .on the dotted lines A B. Fig. 3 is asimilar section as Fig. 1, butwith the burner parts of the lampseparated from the oil container and shell body. Fig. 4 is a plan of thelower burner piece Fig. 3.

The shell of the lamp, comprising base a, waist c, and body d, inclosesand supports a fan mechanism, 6, and the oil container, f, in theordinary way, so that gentle air currents, induced by the fan 6, flowupwardly and around the annular space 9, between the body and oilcontainer, in the manner indi-' cated by the arrows, to feed the burner.The mouth of the oil container is internally screw-threaded as at F, andbetween this month and the body of the shell is the annular outlet 9from thespace g.

The foregoing construction of parts is well known in a lamp of the kindto which the invention refers The invention combines with thescrewthreaded mouth 7' and the annular outlet 9 aforesaid, and with aboundary rim 9 of sald outlet, a burner h, a globe or shade holder imade integral with said burner, and a burner cone a made detachable inrespect of said burner and globe or shade holder.

The burner it carries the wick tube 7L and the wick winder if, and isformed at it with an externally screw-threaded shank to engage thescrew-threaded mouth f of the oil container The globe or shade holder2', within which the globe or shade may seat itself at 3 or upon whichsaid globe or shade may be otherwise supported, is formed at 2' with adepending annular skirting, and

tually attached to the oil container f, forms a most QIIlClGIlt supportfor the globe or shade no matter what its size or weight may be; thecont nuity of the air passages to the wick tube being at the same timemaintained by the perforated plate 2' and the annular skirting 2' Theburner cone a; is formed at m with a depending annular rim and at m withopposite gaps. The latter engage the stem of the wick winder k to alinethe slot 00 of the burner cone with the wick tube, while the rim m fitstightly within a shallow socket g of the globe or shade holder 2' in themanner represented by Fig. 1, this tight fitting sufficiently holdingthe cone a? in position upon the globe or shade holder so as to surroundthe wick tube 5 By the removal of the cone w from the integral burner hand globe or shade holder i the wick of the lamp can be trimmed: byscrewing off the combined burner h and globe holder 2' the oil container7 can be filled.

As hereinbefore stated the object of the invention is the rigid supportof the globe or shade holder 2' by the combination of parts in a lamp ofthe kind to which the invention 1 solely relates.

Having now described my invention What I claim and desire to secure byLetters Patent is I The combination with an oil lamp having an oil Welland an outer shell surrounding the well and in coaction therewithdefining an annular air passage concentric to the Well and having anannular outlet at the adjoining upper ends of the well and the shell, ofa burner comprising a burner body having a Wick tube and formed forengagement in the upper end of the Well, an annular globe holding rimconcentrically circumscribing the body, a plate integrally connectingthe rim and the-body arranged below the plane of the rim to provide inconjunction With the said rim and body a socket concentric to the body,the plate alin- SYDNEY HARRY SHERWOOD.
